Best answer: Can you be homozygous for a blood type?

Are blood types always homozygous?

Both the ABO blood type alleles and the Rh factor genetic information are inherited from our parents, but they are inherited separately. The mother of the child is blood type 0. We know that she is homozygous.

Blood types.

What is the genotype for type A blood?

If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.

What does it mean to be heterozygous for a blood type?

Heterozygous means one dominant & one recessive allele. Since they are Type “B”, the dominant allele is IB, & the only recessive allele for blood type is “i”.

Can a genotype be homozygous?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. … An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

What blood types should not have babies together?

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.

What blood type is iAiA?

The following genotypes will yield these blood types: • iAiA or iAi – Both genotypes produce the A protein (type A). iBiB or iBi – Both genotypes produce the B protein (type B). iAiB – This genotype produces the A and B protein (type AB). ii – This genotype produces no protein (type O).

Can blood type A and B make O?

If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.

Which blood group should not marry?

So Rh +ve man should try to avoid marrying Rh-ve lady. Newborn with erythroblastosis fetalis may need an exchange transfusion. In 1st pregnancy, the problem is less severe but in subsequent pregnancies, a problem becomes more severe.

Which parent determines the blood type of the child?

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
